Cereus Blooms At Night by Shani Mootoo

111653A fierce story of Mala, a multi-layered individual: fiercely protective of her sister after her mother leaves; driven to murder by sexual abuse by her father; an interesting issue of her sanity when she is institutionalized. A book filled with vivid characters. (This is also on the CBC list; last month I recommended Valmiki’s Daughter)
